hello,
I started charging my tab, it got charged till 99% and then i kept on charging it but it didnt went above 99% so i thought may be its because i am using the cell. So i switched it off and kept on charging , The battry icon was charging towards the end part (like the last 10% is getting charged) but in brownish yellow collor (sort of dark orange color) i kept it for charging in this way for like an hour.. Still when i turned on the tab, its 99%. Why so??
I havent rooted it yet! its total stock..
Bought it just 5 days ago..
About half the time, my tab will only go to 99%. Since it's only1% I've never given much thought to it, but I do experience the same problem from time to time.

after reaching to 99%. How long does your tab works??? Are you using p3100 too??

I'm using a p3113. I've never noticed much difference in how long it lasts. Most days, my tablet will last all day whether it charges to 99% or 100%. You really shouldn't see any difference to speak of between a 100% charge and a 99% charge. I personally think it's an overcharge feature to keep it from overcharging. I've actually seen it jump from 100% to 99% one time. If that's the case, then it's a good thing. You could try to bump charge it like I've done to cellphones that won't fully charge. I really wouldn't recommend it since 1% is practically nothing.
Charge it up (powered on) until it's finished.
Unplug it, and turn it off
Plug it back in to charge (still powered off) again, until it says it's finished.It will continue to charge now.
Now unplug it and turn it back on.
Plug the charger back in (powered on) and charge until it says it's finished.
Keep doing this until when you have it powered on, it should say 100%.

The battery charging end is defined with two parmeters: the battery voltage reach a voltage close to 4.2 V and the battery charging current gets under 200mA ( a value I have estimated on my 5110 model) .
If for some reasons the residual current do not get under this limit value ( # 200mA) while the maximum battery voltage is reached , the state of charge stay screened at 99% !!!!!
The 4.2V battery voltage is a safety limit that a Li-Ion battery should not exceed. Most often the battery voltage is stabilized close to this value at the last stage of the charging cycle and the internal charging progam decide that the charging cycle is finished when the battery current gets under a predifined value.
I have given some examples of charging cycles of different smartphones in my blog : http://78michel.unblog.fr (sorry most examples are in french).

So I should stop charging when its 99%?
How many hours does ur tab lasts after charging 99% ?? Cuz mine doesnt lasts even 4 hours .. never charged 99% (just bought it somedays ago) did it yest , its working well now .
Screen takes too much battery ,.. ny way arround it to have better batery life? i saw CM10.1 but it has probs with gsm device so I m not using it ..

I think it is better for the battery life to stop charging if the state of charge level stay on 99%, because the charging current is maintained continuously in the battery and I think this is not so good for the battery life.
You can check the battery current in the battery with diffrents battery monitoring systems. I use Battery Monitor Widget. This is very convenient app. to analyse the charging cycle and the draining of the battery.
Analysis of my 5110 here: http://78michel.unblog.fr/samsung-galaxy-tab-2-10-1-tests/
The screen of these tablets is the most current draining component. At max screen brigthness the battery life is a less than 6 hours on my 5110. The brightness should be setted as low as possible to improve battery life, other componenet such as WiFi... GPS have very low impact on the battery life.....
Hi, I am noob here...
I have replaced my 3000 mah battery tablet which is no longer operate with a 4100mah 3.7V which has bigger capacity. The problem is the original one has 3 leads (red, black and white) while the new one is only 2 wires (red and black).
I have connected the battery and it operates as well until it is fully drained. The problem comes when it is charged, because the battery indicator keeps at 1% and led charging indicator in the tablet keeps yellow (fully charged). This means the battery has not been charged at all.
I suspect the problem is due to the third cable (the white - thermistor??) that is not available in the new battery. Is there any way to make this battery fully functioned in my tablet?
I have done it myself because the service center of this tablet is terrible, very crowded of complaining user, ultra slow delivery and there is no assurance for the availability of the battery.
I am using Advan T2CI (rockchip RK29 based) which is similar to PTM712 HC.
Thank you all for your answer.
Hello, i have my sensation from 2011.
I recently bought him a new battery (2 days ago). !I didn't charge it while being closed yet.
So far i only charged him fully once.
The second time this morning (8 hours of charge time) it was only at ~76%.
In the first 2 hours it charged fast, and when (apparently, i don't know if it really has anything to do with it) the battery temp got lower it stoped charging, when i checked the hour when i woke up the battery started to charge again because the temperature of it raised.
I'm not sure if it has anything to do with battery temperature, I observed this from the screenshot.
When i charge it closed it ussualy charges in ~2 hours. But it barely gets to 3/4 charged when left 8 hours?!?! this is ridiculous.
Do any of you know what might cause the problem?
Is it a genuine HTC Battery? Have you tried it with a different ROM?
Maybe a calibration using Battery Monitor Widget can help.
It is a geniune one.
My other battery had this problem too.
Hey guys first time posting here.
I've had my Z3 for almost 3 months now and have recently noticed some strange things going on with its charging.
Ive been using a third party magnetic charging cable for entire time I've had my phone and they work really well, they charge at a good speed. However, recently the charging time has slowed down dramatically. For example, last night my phone was at 31%, i charged it for 5 and a half hours and it only reached 36%. I checked the battery info tab and it says AC, also the graph showing the battery level shows that the charging is very slow, it says it was charging for the full 5 and 1/2 hours.
-also, no apps were running and the main power user was the screen (as always) which was off.
I don't know what's wrong, I did a battery partition reset a week ago since i was having problems where the phone won't charge past 80% and the reset fixed the 80% problem, but now this is happening.
The charging cable i use is not broken since it works in different power outlets throughout my house and charges the phone normally.
I don't use ROMs and it has the stock factory operating system.
Anyone else have this problem?
Hi guys,
I have another problem with the phone, it doesn't charge - while on and plugged it starts to charge and shortly after that disconnects and doesn't charge at all. While off it looks like charging (the light stays green) but in fact it's just stuck.
Sometimes when I manage to charge it and use it normaly the battery for example shows 80% for the whole day then starts to dicharge rapidly. Additionally the batterytemperature is constantly -31°C in the settings.
I tried to wipe it and fastboot-flashed but it doesn't help.
Had someone similar problem and knows what could be broken? Thanks!
Hi there !
Do you find solution ?
My Mi5s+ dies exactly like this. Tried to replace battery and charging circut from aliexpress but no luck.
the temp sensors is in the battery itself...
I bought 2 replacement batteries & they got same problem....
the original is OK but the capacity is halved already....
Hello,
Could you solve the problem or find the faulty part??
